11.1 The simulation capabilities of EXPLOITS

So far as the author is aware, the simulation capabilities of EXPLOITS, and of the PHOENICS code on which it is based, encompass all that are offered by any other risk-assessment simulator, as well as many more.

The "many more" include: two-phase, multi-fluid, IMMERSOL, stresses-in-solids, and free-surface.

Moreover, because PHOENICS is being used for many other purposes, it is constantly acquiring new capabilities, some of which may be useful to EXPLOITS.

Further, because PHOENICS works equally well in a personal computer a work-station, a super-computer or a parallel-processor machine, EXPLOITS enables computations to be performed economically, even when the grid size is very large.

The Virtual-Reality User Interface already, it is believed, enables hazard specialists without special knowledge of CFD techniques to use EXPLOITS for themselves.

The remote-computing capabilities offered by CHAM through its MICA project also enable users, if they wish, to enjoy the "metered use" of EXPLOITS on an off-site machine.

Additionally, if they wish, they can call for assistance and advice on setting up the problem, on interpreting the results, or on drawing practical conclusions from them.

EXPLOITS can take in its initial geometrical data from a CAD file; and it can format its output so that it can be displayed by way of any package preferred by the user.

CHAM is ready, now, to provide hazard-analysis services to individual clients in whatever way they require, eg:

(a) Provision of the EXPLOITS interface, connected by modem to CHAM;
(b) Provision of a stand-alone EXPLOITS-PHOENICS package, for PC or
work-station, with or without modem connexion;
(c) Provision of the results of simulations, performed by CHAM, of
situations specified by clients in any way they please;
(d) Assistance in the preparation of "safety cases".
(e) Further, if sufficient interest exists, CHAM would like to form
"EXPLOITS Users Club", members of which would:

• agree to spend a minumum sum with CHAM each year for EXPLOITS- related services (eg 10 000 pounds sterling, which buys 20 man- or computer-days at commercial rates);
• pay for these services at two-thirds of the commercial rate;
• participate in an advisory committee on EXPLOITS development.
